Use this winter swimming pool cover with all inground pools, Kayak, Fanta-Sea and other on-ground rectangular pools. Dollar for dollar, you will not buy a better cover! This cover is made from polyethylene fabric, which is the toughest, most durable material available. It has been time tested and will not crack, split or tear from the cold. Covers are lightweight, which makes them easier to put on and take off your pool. In addition, they take up less room to store. The "Hold-tite" reinforced seams will last longer. They will not rip, fray or come apart. Kayak and Kayak Pools are trademarks of Kayak Pool Corporation. SaveMoreOnPoolsupplies is not affiliated with Kayak Pool Corporation or Kayak Pools.
